Abstract: 1,052,123. Magnetic tape recorders. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Feb. 20, 1964 [Feb. 20, 1963]. No. 7236/64. Heading G5R. Magnetic tape transducing apparatus has a easing with an opening for edgewise insertion and removal of tape spools, the apparatus including guides for directing the spools to positions where they are aligned with driving members for the spools, and positioning means for causing or enabling the tape spools and driving members to engage with one another. Referring to Fig. 2, an opening in the casing (not shown) allows spools to be inserted in guides 4 which slope downwards slightly, and the opening may be closed by a flap 2. When the flap is closed, levers 7 operated by the flap lower the guides 4 so that the spools engage supporting discs 9, a pressure device 18 mounted on the flap presses the tape into contact with a capstan 17, and the flap operates a switch 11 which switches on the drive. The drive-shaft 12 is coupled to the supporting discs 9 by belts 20 and 21 which are slightly tensioned to drive the spools in opposite directions. For fast wind or re-wind the flap 2 is opened and is displaced to left or right thereby rotating crank arm 25 and the support 22 of the drive shaft so that the tension in one of the belts 20 and 21 is increased whilst that in the other is decreased. Stops 29 prevent such displacement of the flap when it is closed and the capstan is operative; a cam member 28 allows the switch 11 to be operated when the flap is displaced and slightly open. A latch may be provided for locking the flap in its closed and in its slightly open positions, Fig. 3 (not shown). A switch for switching into the record condition may be arranged so that it can be operated when the flap is open and is only held in the actuated position when the flap is closed.

Abstract: 1,228,627. Cathode-ray storage tubes; PN junction arrays. WESTERN ELECTRIC CO. Inc. 17 Oct., 1968 [18 Oct., 1967], No. 49344/68. Headings H1D and H1K. In a cathode-ray storage tube such as a camera pick-up tube or a scan converter tube having a target structure comprising an array of rectifying junction diode regions 21 on a substrate 20, the diode regions being reverse biased by a scanning reading beam, the recombination velocity of the electron-hole pairs produced at the input surface of the target structure by light or energetic electrons is reduced by the provision of an impurity gradient region 24 within the substrate adjacent the input surface. The gradient is shown by the curve 32 of Fig. 3 and has the effect of repelling minority carriers from the input surface of the target, thereby causing them to diffuse towards the nearest diode junctions, and also facilitates the making of an ohmic contact to the substrate. The region 31 of the substrate has a uniform resistivity of at least 0À1 ohm-cm., e.g. 0À1 to 10 ohm-cm., and the gradient region has a sheet resistivity of 10 to 600 ohms per square. The gradient region is less than a micron thick. With an N-type silicon substrate the dopant impurity may be phosphorous, the concentration of charge carriers over the gradient region varying from 5 x 10<SP>14</SP> to 6 x 10<SP>20</SP> per c.c. The target structure is formed as follows:-a slice of monocrystalline N-type silicon, 0À5 to 15 mils thick, is polished to form the substrate 20 and then oxidized to form a layer 22 of silicon dioxide in which an array of apertures 8 microns in diameter, 20 microns centre-to-centre, is etched. Boron is then diffused into the substrate through the array of apertures to form the P-type regions 21. The impurity gradient region 24 is formed by diffusing phosphorus, into the substrate, e.g. from PBr 3  plus nitrogen and a trace of O 2  or from elemental phosphorus, at temperatures of, e.g., 750 to 1050 C. and for a time of, e.g., 5 to 30 minutes. A contact to the region 24 may be made by vacuum-evaporating gold thereon or by directly contacting the phosphorus-doped substrate. In an alternative target structure N-type regions may be diffused into a P-type substrate. The diode array surface of the target may be covered with a semiinsulating layer as described in Specification 1,222,445 and in a camera tube, the lightreceiving surface may be covered with an antireflection coating. The reverse biasing of the diode junctions may be achieved by secondary electron emission. Electron-hole pairs may be created at the input surface of the target by a writing beam in a scan converter tube or by an electron image from a photo-emitter.

A method of separating feebly magnetic ores in which the material is contacted by ferromagnetic bodies in a magnetic field is characterised in that after being removed from the magnetic field the bodies are separated from each other to remove their residual magnetism after which they are returned to the field of influence of the magnetic field. The bodies which are preferably balls may be separated by being fed onto an inclined vibrating tray where they are subjected to the action of an alternating magnetic field. Jets of liquid may also be used and obstacles may be set up in the path of the bodies so that they may collide with them.

Abstract: 1,238,334. Photo-electric detector circuits. INTERNATIONAL COMPUTERS Ltd. Aug.18, 1969 [Aug.27, 1968], No.40801/68. Heading G1A. [Also in Division H3] A variable impedance device such as a photodiode 3 is connected in the e-b circuit of a transistor T2 to turn it on or off, a current source such as T1 being controlled by T2 to supply a first current, adjustable at R2 for example, to the photo-diode 3 when T2 is on, and a second current of lower magnitude, when T2 is off. The transistor T2 controls an output transistor T3, and the circuit has a hysteresis due to the reciprocal coupling of T1, T2. This ensures that erraneous switching does not occur, when for example the light source is not wholly constant in a tape-reading application. When T2 is on, it shorts out resistors R5, R6 and causes a relatively positive potential to occur at T1 base to increase its collector current. When T2 goes off due to the incidence of light reducing the resistance of the photo-cell 3 the base voltage of T1 falls and reduces its collector current.

Abstract: 1,265,199. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 22 Sept., 1969 [7 Oct., 1968], No. 46504/69. Heading H1K. [Also in Division B6]  In the manufacture of a semi-conductor device such as the Si transistor shown, a masking layer 18, e.g. of Si 3 N 4 , is selectively etched by a first etchant, e.g. ammonium hypophosphate, to provide an opening through which a dopant such as P or As is diffused to form a region 24. During this diffusion, which may take place from the vapour phase in an oxidizing atmosphere, a film 26 of SiO 2  forms in the opening, and this is subsequently removed by an etchant which attacks the film 26 but not the masking layer 18. A buffered solution of hydrofluoric acid and ammonium fluoride is suitable for this purpose. In the embodiment a layer 16 of SiO 2  is initially formed on the Si body 10 by oxidation or pyrolytic deposition, and an additional etching step using the buffered solution is required to expose the Si surface. The Si 3 N 4  layer 18 is deposited from the vapour phase. Part of the base region 12 is also exposed and Al electrodes are deposited and etched to shape. Alternatively platinum silicide, palladium silicide or Mo may be employed. Multi-layer electrodes including Cr-Ag-Cr or Ti-Ag-Cr structures may also be used, in which case a further sputtered layer of SiO 2  may be provided to mutually insulate the different electrode levels.
